[ Upstream commit 9d75f089 ] tpm_ibmvtpm_probe() calls ibmvtpm_reset_crq(ibmvtpm) without having yet set the virtual device in the ibmvtpm structure. So in ibmvtpm_reset_crq, the phype call contains empty unit addresses, ibmvtpm->vdev->unit_address. Signed-off-by:

[ Upstream commit 921cc294 ] The way the mask is generated in regmap_field_init() is wrong. Indeed, a field initialized with msb = 31 and lsb = 0 provokes a shift overflow while calculating the mask field. On some 32 bits architectures, such as x86, the generated mask is 0, instead of the expected 0xffffffff. This patch uses GENMASK() to fix the problem, as this macro is already safe regarding shift overflow. Signed-off-by:

[ Upstream commit 4b200b46 ] This fixes a several year old regression that I found while trying to get the Yoga 3 11 to work. The ideapad_rfk_set function is meant to send a command to the embedded controller through ACPI, but as of c1f73658, it sends the index of the rfkill device instead of the command, and ignores the opcode field. This changes it back to the original behavior, which indeed flips the rfkill state as seen in the debugfs interface. Signed-off-by:

[ Upstream commit 6f6a6fda ] If updating journal superblock fails after journal data has been flushed, the error is omitted and this will mislead the caller as a normal case. In ocfs2, the checkpoint will be treated successfully and the other node can get the lock to update. Since the sb_start is still pointing to the old log block, it will rewrite the journal data during journal recovery by the other node. Thus the new updates will be overwritten and ocfs2 corrupts. So in above case we have to return the error, and ocfs2_commit_cache will take care of the error and prevent the other node to do update first. And only after recovering journal it can do the new updates. The issue discussion mail can be found at: https://oss.oracle.com/pipermail/ocfs2-devel/2015-June/010856.html http://comments.gmane.org/gmane.comp.file-systems.ext4/48841 [ Fixed bug in patch which allowed a non-negative error return from jbd2_cleanup_journal_tail() to leak out of jbd2_fjournal_flush(); this was causing xfstests ext4/306 to fail. -- Ted ] Reported-by:

In process of the suspend flow the devices first have to exit from the power gating state (runtime pm resume). If we do not handle the confirmation interrupt after sending PG_ISOLATION_EXIT message, we may receive it already after the suspend flow has changed the device state and interrupt will be interpreted as a spurious event, consequently link reset will be invoked which will prevent the device from completing the suspend flow kernel: [6603] mei_reset:136: mei_me 0000:00:16.0: powering down: end of reset kernel: [476] mei_me_irq_thread_handler:643: mei_me 0000:00:16.0: function called after ISR to handle the interrupt processing. kernel: mei_me 0000:00:16.0: FW not ready: resetting Cc: <stable@vger.kernel.org> #3.18+ Cc: Gabriele Mazzotta <gabriele.mzt@gmail.com> Link: https://bugzilla.kernel.org/show_bug.cgi?id=86241 Link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=770397Tested-by:

[ Upstream commit bdf96838 ] The commit cf108bca: "ext4: Invert the locking order of page_lock and transaction start" caused __ext4_journalled_writepage() to drop the page lock before the page was written back, as part of changing the locking order to jbd2_journal_start -> page_lock. However, this introduced a potential race if there was a truncate racing with the data=journalled writeback mode. Fix this by grabbing the page lock after starting the journal handle, and then checking to see if page had gotten truncated out from under us. This fixes a number of different warnings or BUG_ON's when running xfstests generic/086 in data=journalled mode, including: jbd2_journal_dirty_metadata: vdc-8: bad jh for block 115643: transaction (ee3fe7 c0, 164), jh->b_transaction ( (null), 0), jh->b_next_transaction ( (null), 0), jlist 0 - and - kernel BUG at /usr/projects/linux/ext4/fs/jbd2/transaction.c:2200! ...

[ Upstream commit 93563a6a ] For TX transactions, the TXCOMP bit in the Status Register is cleared when the first data is written into the Transmit Holding Register. In the lines from at91_do_twi_transfer(): at91_twi_write_data_dma(dev); at91_twi_write(dev, AT91_TWI_IER, AT91_TWI_TXCOMP); the TXCOMP interrupt may be enabled before the DMA controller has actually started to write into the THR. In such a case, the TXCOMP bit is still set into the Status Register so the interrupt is triggered immediately. The driver understands that a transaction completion has occurred but this transaction hasn't started yet. Hence the TXCOMP interrupt is no longer enabled by at91_do_twi_transfer() but instead by at91_twi_write_data_dma_callback(). Also, the TXCOMP bit in the Status Register in not a clear on read flag but a snapshot of the transmission state at the time the Status Register is read. When a NACK error is dectected by the I2C controller, the TXCOMP, NACK and TXRDY bits are set together to 1 in the SR. If enabled, the TXCOMP interrupt is triggered at the same time. Also setting the TXRDY to 1 triggers the DMA controller to write the next data into the THR. Such a write resets the TXCOMP bit to 0 in the SR. So depending on when the interrupt handler reads the SR, it may fail to detect the NACK error if it relies on the TXCOMP bit. The NACK bit and its interrupt should be used instead. For RX transactions, the TXCOMP bit in the Status Register is cleared when the START bit is set into the Control Register. However to unify the management of the TXCOMP bit when the DMA controller is used, the TXCOMP interrupt is now enabled by the DMA callbacks for both TX and RX transfers. Signed-off-by:

[ Upstream commit a5dd4b4b ] The commit referenced below deferred waiting for command completion until the start of the next command, allowing hardware to do the latching asynchronously. Unfortunately, being ready to accept a new command is the only indication we have that the previous command is completed. In cases where we need that state change to be enabled, we must still wait for completion. For instance, pciehp_reset_slot() attempts to disable anything that might generate a surprise hotplug on slots that support presence detection. If we don't wait for those settings to latch before the secondary bus reset, we negate any value in attempting to prevent the spurious hotplug. Create a base function with optional wait and helper functions so that pcie_write_cmd() turns back into the "safe" interface which waits before and after issuing a command and add pcie_write_cmd_nowait(), which eliminates the trailing wait for asynchronous completion. The following functions are returned to their previous behavior: pciehp_power_on_slot pciehp_power_off_slot pcie_disable_notification pciehp_reset_slot The rationale is that pciehp_power_on_slot() enables the link and therefore relies on completion of power-on. pciehp_power_off_slot() and pcie_disable_notification() need a wait because data structures may be freed after these calls and continued signaling from the device would be unexpected. And, of course, pciehp_reset_slot() needs to wait for the scenario outlined above. Fixes: 3461a068 ("PCI: pciehp: Wait for hotplug command completion lazily") Signed-off-by:

[ Upstream commit 2fa19535 ] If objects are moved back from system memory to VRAM (and spice id created again) memory is already initialized so we need to set flag to not clear memory. If you don't do it after a while using desktop many images turns to black or transparents. Signed-off-by:

[ Upstream commit 64ad6c48 ] Since commit bafc9b75 ("vfs: More precise tests in d_invalidate"), mounted subvolumes can be deleted because d_invalidate() won't fail. However, we run into problems when we attempt to delete the default subvolume while it is mounted as the root filesystem: # btrfs subvol list / ID 257 gen 306 top level 5 path rootvol ID 267 gen 334 top level 5 path snap1 # btrfs subvol get-default / ID 267 gen 334 top level 5 path snap1 # btrfs inspect-internal rootid / 267 # mount -o subvol=/ /dev/vda1 /mnt # btrfs subvol del /mnt/snap1 Delete subvolume (no-commit): '/mnt/snap1' ERROR: cannot delete '/mnt/snap1' - Operation not permitted # findmnt / findmnt: can't read /proc/mounts: No such file or directory # ls /proc # Markus reported that this same scenario simply led to a kernel oops. This happens because in btrfs_ioctl_snap_destroy(), we call d_invalidate() before we check may_destroy_subvol(), which means that we detach the submounts and drop the dentry before erroring out. Instead, we should only invalidate the dentry once the deletion has succeeded. Additionally, the shrink_dcache_sb() isn't necessary; d_invalidate() will prune the dcache for the deleted subvolume.

[ Upstream commit 45c44b5f ] Increase the default init stage change timeout from 15 seconds to 30 seconds. This resolves issues we have seen with some adapters not transitioning to the first init stage within 15 seconds, which results in adapter initialization failures.
